5 degree F. increase in July temperature with 8- 15 degree F. increase in July Heat Index Rising sea levels 13 to 20 feet Rising Sea Levels 13 to 20 Feet Loss of 40 % of living Species
4
HEAT WAVE Aug. 2003 30,000 excess deaths in Europe Doubling incidence of heat waves Am J Pub Health 2004;94(9) NASA
5
Rising Sea Level Huge coastal refugee population From storm surge Increase in river flooding Inundation of rich delta farmland Saltwater infiltration of clean drinking water Boston Globe 9/05
6
Ocean Acidity and Temperature Increase CO2 buffered, increases acidity Temperature and acid- bleaches coral 30% bleached worldwide 60% at risk 50% of fish biodiversity in coral reefs (tropical rainforest of the ocean)
7
Coal plants are the single largest source of CO2 emissions in the US Transportation 33.1% (Oil) Industrial 15% Residential Commercial Commercial 4.0% Other Electricity Other Electricity Generation 7.0% Electricity Generation from coal 33.8% Source: EPA 2006 Residential 6.6%
8
80% reduction path Geothermal CSP Efficiency Wind Biofuels Biomass Solar Efficiency + renewables path to 60-80% CO2 reductions Write in white
9
Coal Nuclear Nat’l Gas Hydro Biomass Geothermal, Landfill gas Solar Electricity Supply, IEER Scenario Geothermal hot rock Wind Combined heat & Power wwwIEER.org
10
U.S. Electrical Energy Consumption Buildings responsible for ½ CO2 emissions Lighting HVAC systems
11
Architecture 2030 Challenge Require all new buildings to utilize 50% of prior fossil fuel requirements Increase efficiency requirement by 10% each 5 years Net CO2 zero by 2030 Mount Airy, NC library

Clean Alternative Energy Wind Solar Concentrated Solar Power Geothermal Tide Wave Biofuels
13
Solar Energy More costly per unit of energy Can be on the grid or off. Passive or active www.energy.state.md.us
14
Renewable Electricity Standards PA: 8% by 2020 23 States + D.C. Standard Standard and Goal Voluntary Goal 15 states have already raised or accelerated targets 13 states have requirements of 20% or higher
